Breathing Patterns Flashcards
define apnea
Lack of airflow to the lungs for >15 seconds
what conditions are associated with apnea?
Airway obstruction, cardiopulmonary arrest, alterations of the respiratory center, narcotic overdose
define Biot’s respirations
Constant increased rate and depth of respiration followed by periods of apnea of varying lengths
what conditions are associated with Biot’s respirations?
Elevated ICP, meningitis
define bradypnea
Ventilation rate <12 breaths per minute
what conditions are associated with bradypnea?
Use of sedatives, narcotics, or alcohol; neurologic or metabolic disorders; excessive fatigue
define Cheyne-Stokes respirations
Increasing depth of ventilation followed by a period of apnea
what conditions are associated with Cheyne-Stokes
respirations?
Elevated ICP, CHF, narcotic overdose
define hyperpnea
Increased depth of ventilation
what conditions are associated with hyperpnea?
Activity, pulmonary infections, CHF
define hyperventilation
Increased rate and depth of ventilation resulting in decreased PCO2
what conditions are associated with hyperventilation?
Anxiety, nervousness, metabolic acidosis
define hypoventilation
Decreased rate and depth of ventilation resulting in increased PCO2
what conditions are associated with hypoventilation?
Sedation or somnolence, neurologic depression of respiratory centers, overmedication, metabolic alkalosis
define Kussmaul respirations
Increased regular rate and depth of ventilation
